Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compound for an organic electroluminescent device and an organic electroluminescent device including the compound.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compound for an organic electroluminescent device and an organic electroluminescent device including the same, and more particularly to a compound for an organic electroluminescent device capable of improving the luminous efficiency of the organic electroluminescent device, Device.

The organic electroluminescent device has a simpler structure than other flat panel display devices such as a liquid crystal display (LCD), a plasma display panel (PDP) and a field emission display (FED) And has a high response speed and a low driving voltage, so that it is being actively developed to be used as a light source for a flat panel display such as a wall-mounted TV or a backlight of a display, a lighting, and a billboard.

In general, when a direct current voltage is applied to an organic electroluminescent device, holes injected from the anode recombine with electrons injected from the cathode to form an electron-hole pair exciton, and the exciton returns to a stable ground state, It is converted into light by transmission to the material.

In order to improve the efficiency and stability of the organic electroluminescent device, a laminated organic thin film is formed between two opposing electrodes by CW Tang et al. Of Eastman Kodak Company, and a low voltage driven organic electroluminescent device is reported (CW Tang, SA Vanslyke, Applied Physics Letters, vol. 51, p. 913, 1987), studies on organic materials for multilayer thin film structure organic electroluminescent devices have been actively conducted. The efficiency and lifetime of such a stacked organic electroluminescent device are closely related to the molecular structure of the material constituting the thin film. For example, the quantum efficiency is greatly influenced by the structures of the light emitting material, the hole transporting layer material, and the electron transporting layer material among the materials constituting the thin film, and when the thermal stability is deteriorated, the crystallization of the material occurs at a high temperature or a driving temperature, Is shortened.

Particularly, among the thin film constituting materials of the organic electroluminescent device, a luminescent material which can be largely divided into a host material and a luminescent material (dopant) is distinguished by fluorescence and phosphorescence depending on the luminescent mechanism. In the case of using a luminescent material, A fluorescent dopant material capable of satisfying higher efficiency, color purity, and long life is required.

The present invention provides an organic electroluminescent compound which is excellent in electrical stability, can realize high efficiency, high color purity and long life, emits a purple emission and can be used for a fluorescent light emitting layer as a dopant, and an organic electroluminescent device including the compound have.

In addition, the organic electroluminescent device of the present invention can realize high efficiency, high color purity and long life time by hydrogenating an anthracenone and substituting an amine by an anthracenone.

The external quantum efficiency was obtained by measuring the amount of light at that time using a luminance meter (Minolta CS-2000) while increasing the voltage from 0 V to 5 V, and dividing the measured light quantity value by the electron density current value. In addition, the color coordinates were measured using a luminance meter (Minolta CS-2000). The lifetime (T90) was measured by changing the luminance while continuously applying a constant current of 50 mA / cm < ² > and measuring the elapsed time at the time when the luminance was 90% based on the initial luminance as 100%.

According to Tables 1 and 2, as a result of using the compounds 1 to 9 according to the present invention in an organic electroluminescent device comprising a dopant, high color purity was exhibited by short wavelength luminescence as compared with Comparative Examples 1 and 2, And it was confirmed that it exhibits excellent characteristics.
